Diffrient World Task Chair from Humanscale

Diffrient World marks Humanscale's first foray into all-mesh task seating. Like its mesh-backed forerunner, Liberty, the Diffrient World chair's tri-panel backrest hugs the body to provide tailor-made lumbar support, while its mesh seat eliminates contact stress under the thighs. But Diffrient World’s major innovation is its mechanism-free recline action, which leverages two parts of the chair’s frame and the laws of physics to provide automatic, balanced support throughout the full range of recline. No chair is more intuitive, creating the ultimate user-friendly sitting experience.

The laws of physics promote the balanced support in the full range of its automatic recline. A truly intuitive task chair, it requires no ‘user knowledge’ or control levers. Modern design demands simplicity and performance. HumanScale has achieved this plus the industry’s best 15-Year, 24/7 Warranty! CAL 133 approved and 97% recyclable. Available in Basic models, Armless models and Fully-Adjustable arms models. Choose Black, Gray or White frames with a large range of colors and seat fabrics; multiple cylinder heights; even stainless steel base caps are available.
